Radiographic evaluation of osteochondritis dissecans of the humeral capitellum: A systematic review.

Abstract Background The purpose of this study was to evaluate radiographic-based classification systems for osteochondritis dissecans (OCD) of the capitellum and determine their agreement with intraoperative findings. Methods Using PRISMA guidelines, we analyzed 44 studies utilizing a total of 19 classification systems. Results Magnetic resonance imaging (MRI)-based systems showed better predictive value of intraoperative staging, and the Itsubo and Kohyama classifications showed best predictive value for lesion stability. Conclusions No classification system effectively correlated with intraoperative findings. A combination of radiograph, MRI, and computed tomography will most accurately determine OCD lesion stability. Level of evidence IV, Systematic Review.
